Commercial HVAC Pittsburgh Businesses Can Plan Around.
When a rooftop unit dies in July, a restaurant dining room empties and a server room starts cooking its own hardware. Most commercial HVAC failures we respond to were visible months earlier — a slipping belt, a fouled condenser coil, a refrigerant charge drifting low. That’s why our commercial work is built around scheduled preventive maintenance instead of heroic emergency repairs: quarterly inspections catch the $200 problem before it becomes the $12,000 replacement, and contract customers jump the queue when Pittsburgh weather stacks the call board.
We’re equally honest about the repair-or-replace line. A 20-year-old RTU with a cracked heat exchanger doesn’t deserve another compressor; a 9-year-old unit with a failed economizer usually does. We quote both paths with real numbers, coordinate crane lifts and curb adapters for replacements, pull the permits, and handle the refrigerant transition rules that are retiring older R-410A equipment. Your building gets an equipment plan, not a sales pitch.
Why Pittsburgh Businesses Put Machi on Contract.
Preventive Maintenance Contracts
Quarterly filter, coil, belt, and refrigerant service on a documented schedule, with written condition reports after every visit — the paperwork property managers and franchise operators actually need. Contract customers get priority emergency dispatch, 24/7.
Rooftop Unit Specialists
Carrier, Trane, Lennox, York — we repair, replace, and retrofit RTUs from 3 to 25 tons. Crane coordination, curb adapters, economizer repair, and gas heat sections are all handled in-house, scheduled around your operating hours.
Three Trades, One Invoice
The same contract can cover your HVAC, your backflow testing and grease traps, and your lighting retrofits and panel work. One number to call, one vendor to onboard, one invoice for the owner’s books.

Commercial HVAC Systems We Handle in Pittsburgh.
Rooftop Units (RTUs)
The workhorse of Pittsburgh flat-roof commercial buildings — and the equipment most often run to failure. We service every major brand, and when replacement is the right call we manage the whole lift: structural check, crane scheduling, curb adapter fabrication, and startup documentation.
- RTU repair — Carrier, Trane, Lennox, York
- Replacement with crane coordination
- Curb adapters and retrofit fits
- Economizer repair and fresh-air compliance
- Gas heat section service
Split Systems, VRF & Controls
Not everything sits on the roof. We service commercial split systems, dedicated server-room cooling, VRF/VRV systems, and the thermostats and building controls that run them — including make-up air for restaurant kitchens.
- Commercial split system repair and replacement
- Server-room mini-split cooling
- VRF / VRV diagnostics and service
- Thermostat and building-control upgrades
- Ventilation and make-up air units
Maintenance Contracts
A commercial HVAC preventive maintenance plan tuned to your equipment count and operating hours. Quarterly visits keep warranties valid, energy bills flat, and surprise failures rare — and every visit ends with a written condition report.
- Quarterly filter, coil, and belt service
- Refrigerant charge and leak checks
- Priority 24/7 emergency dispatch
- Written condition reports per visit
- Multi-site and property-management plans
What Commercial HVAC Costs in Pittsburgh.
Business owners ask for numbers first, so here they are. Commercial diagnostic calls run $149 to $249 depending on equipment access. Maintenance contracts are priced per unit per quarter and scale with equipment count — most single-RTU storefronts land near the bottom of the range. Replacements are quoted after a site walk because tonnage, curb condition, and crane access drive the price; you get a written, itemized quote before anything is ordered.

Commercial HVAC Pittsburgh FAQs.
Questions we hear before every first service call. Can’t find yours? Call (866) 962-7160 — a live dispatcher answers 24/7.
Do you offer commercial HVAC maintenance contracts in Pittsburgh?
Yes — that’s the core of our commercial business. A commercial HVAC maintenance contract includes quarterly filter, coil, belt, and refrigerant service, written condition reports after every visit, and priority 24/7 emergency dispatch. Plans are priced per unit per quarter and scale from single-storefront RTUs to multi-site property portfolios.
What does commercial HVAC preventive maintenance include?
Each quarterly visit covers filters, condenser and evaporator coil cleaning, belt and bearing inspection, refrigerant charge verification, electrical connection checks, condensate drain service, and controls testing. Heating visits add heat exchanger and gas section inspection. Everything is documented so you have a service history for warranties, insurance, and tenant records.
Do you service rooftop units (RTUs)?
Yes — RTUs are the majority of our commercial HVAC Pittsburgh work. We repair Carrier, Trane, Lennox, and York units from 3 to 25 tons, and when replacement makes more sense we handle crane scheduling, curb adapters, structural checks, and startup commissioning as one managed job, scheduled around your business hours.
How fast can you respond to a commercial HVAC emergency?
Contract customers get priority dispatch — typically 2 to 4 hours anywhere in Allegheny County, 24/7 including holidays. Non-contract emergency calls are worked into the board in order received. A restaurant with no cooling on a Saturday in July is exactly the call our emergency HVAC line exists for.
Do you work with property managers and multi-tenant buildings?
Yes. Multi-site maintenance plans with consolidated invoicing and per-visit condition reports are built for property management. Your tenants call one number, your owner gets one invoice, and every unit across the portfolio sits on the same documented service schedule.
What types of businesses do you serve?
Offices, restaurants, retail storefronts, medical and dental offices, churches, and light-industrial properties across Greater Pittsburgh. If your building runs RTUs, split systems, or VRF and downtime costs you money, it fits our commercial book.
Can Machi handle plumbing and electrical for my building too?
Yes — that’s the point of a multi-trade contractor. The same account covers commercial plumbing (backflow testing, grease traps, fixture service) and commercial electrical (lighting retrofits, panel upgrades). One vendor to onboard, one number to call, one invoice.
